DELlVERY-CHUTE FOR COAL-WAGONS.

SPECIFICATION forming part of Letters Patent No. 658,600, dated September 25, 1900.

Application filed August 22, 1899- Serial No. 728,057- (No model.)

To all whom it may concern;-

Be it known that I, SAMUEL W. TAYLOR, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Delivery-Chutes for Coal WVagons, Oars, dad, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved construction of delivery-chute for use on coal wagons and cars; and it consists in the construction substantially as hereinafter set forth.

The principal object of my invention is to provide a Wagon or car with means for automatically delivering the coal or other mate-. rial from the side of the wagon.

A further object of my invention is to provide means for feeding the material in the said wagon or car to a centrally-disposed conveyer, thereby insuring the complete emptying of the Wagon and delivering the contents of said wagon to one side thereof.

A still further object of my invention is to provide a wagon or car with a centrally-disposed conveyer and means for operating said conveyer to feed the material through one side of the body of the vehicle and means for simultaneously elevating each end of the vehicle-botto m,so that the material may be gradually guided or fed to the said centrally-disposed conveyer.

A still further object of my invention consists in providing an improved arrangement of gearing and means for operating the same and multiplying the power for elevating the two sections of the bottom of the wagon.

A still further object of my invention is to 0 provide improved clutch mechanism',connected with the means for elevating the bottom sections of the wagon, whereby the operating mechanism for the elevators may be disengaged from the driving mechanism and the 5 said bottom sections returned to normal position, this construction also enabling one of the bottom sections of the vehicle to be elevated independent of the other for the purpose of unloading one-half of the said vehi- 50 ole, if it should be so desired.

In order to enable others skilled in the art l to which my invention most nearly appertains to understand and use the same, I will now proceed to describe it, with reference to the accompanying drawings, in which similar letters of reference are used to designate simi lar parts.

In the said drawings, Figure 1 is a side elevation of a wagon embodying my invention. Fig. 2 is a'central longitudinal sectional view of the same. Fig. 3 is a side elevation illustrating the opposite side of the wagon to that shown in Fig. 1, the wheels and running-gear being omitted. Fig. t is a top plan view of the wagon, the delivery end of the chute being partially broken and shown in section for the purpose of more clearly illustrating the gate provided in this end of the chute. Fig. 5 is an enlarged detail sectional view through one of the clutch mechanisms for throwing the elevators in and out of gear with the driving mechanism.

In carrying out my invention I provide a transversely-disposed chute A, located in the central portion of the bottom of the wagon, the said chute being closed at one end and open at the other and secured to the wagon or car body in any suitable man ner. Located in the chute A is an ordinary spiral screw conveyer A, adapted to rest loosely therein, the contour of the bottom of the chute conforming in shape to the circular blades of the conveyer, and one end of the conveyer-shaft passes through the closed end of the chute and through the side of the wagon and has provided on this extended end a sprocketwheel B, which is geared, by means of the chain 0, to a smaller sprocket wheel D, mounted on the main driving-shaft E. This shaft E is provided on the end opposite to the wheel B with a crank F, by means of which the driving-shaft is operated and motion transmitted to the screw conveyer-A.

The bottom of the wagon is formed in two sections G and G, the inner ends of each section being secured to the shafts a 0/, which shafts are pivotally mounted in the side walls of the wagon-bod y. Located a short distance above the shafts a a are the shafts b b, which are also journaled in the side walls of the wagon-body and extend a short distance beyond the said side walls,the purpose of which will be hereinafter described. Secured to each of the shafts b b by means of rivets or otherwise are the cables or chains 0 c, the said cables passing toward the respective ends of the wagon and over the sheaves d d, respectively, from whence they then pass downwardly and are secured by any suitable means to the other ends of the bottom sections G G, as clearly illustrated in Figs. 2 and 4 of the drawings. The sheaves d d are supported in suitable brackets e e, secured to the front and rear end of the wagon-body at or near the upper edges thereof. .On one end of each of the shafts b b I provide the gear-wheels H H, which mesh with an intermediate gear 1, secured on a stub-shaft journaled in the side wall of the wagon-body, which gear I meshes with a pinion J, rigidly mounted on the conveyer-shaft B. Thus as the driving-shaftE is operated by means of the crank F motion is transmitted to the conveyer-shaft B through the medium of the sprockets B and D and the chain 0, which in turn transmits motion to the shafts b I) through the medium of the intermeshing gears H H, heretofore described, and causes the cables 0 c to wind around the shafts b b, respectively, and gradually raise or elevate the outer. ends of each of the bottom sections G G simultaneously, which operation feeds the coal or other material to the delivery-chute A. From thence it is delivered by means of the conveyor A sidewise through the open end of the chute A.

The chute A is provided at its open end with invention as particularly adapted for use as i a coaldelivery wagon or car, it will of course a pivoted gate A which operates in a slot formed in the chute-casing outside of the wagon-body.

On the projecting ends of the shafts b b, on i Wagons for delivering macadam to roadbeds 1 in the construction of roads,whereit has been i found especially desirable to deliver the material sidewise from the wagon. VV'hen using the side opposite the gear H H, I provide the ratchet-wheels g g, the said ratchet-wheels being loosely mounted on the said shafts and made to revolve therewith by means of a feather h, which engages a slot h, formed in the ends of the shafts, as illustrated in Fig. 5 of the drawings. The brackets 2 which are secured to the side Wall of the Wagon-body, form an additional bearing for this end of the shafts b b and also serve to retain the ratchets g g in position. The outer ends of each of the shafts b b' are provided with an annular recess j, adapted to receive the bifurcated ends of the clutch-levers k k, the said clutchlevers being pivotally mounted at or near their centers to bosses Z Z, carried by the wagon-body. Located at a suitable distance above each of the ratchets g g are the pawls m m, pivoted by means of suitable screws to the side wall of the wagon-body, the said pawls being adapted to engage with the ratchets g g and prevent the backward movement of the shafts b b.

m m is provided with a finger 'n n, on the under side of each of which bears one end of a spring 0 0, the said springs 0 0 being coiled around the bosses Z Z and having their other ends bent under the brackets it", as illustrated in Fig. l of the drawings, these springs tion by gravity.

Each of the said pawls serving to keep the pawls normally in engagement with the ratchets g g for the purpose heretofore described. Thus when the bottom sections G G have been elevated in the manner heretofore described and it is de sired to return either or both of them to normal position the clutch-levers k k are operated, which operation slides the shafts b b longitudinally and disengages the gears on the opposite ends of said shafts from the intermediate gear I, which renders these particular shafts idle. The pawls m m are then disengaged from their respective ratchets g g by depressing the arms 12 n, which allows the shafts b b to revolve in an opposite direction and unwind the cables 0 c, and the bottom sections G G will return to normal posi- After this has been done the clutch-levers k k are operated to return the shafts d d to their normal positions and in engagement with the driving mechanism.

If it is desired to divide the wagon-body into two separate compartments, a sliding partition 1", adapted to guideways 7, formed on the inner sides of the wagon-body, may be employed, as illustrated in dotted lines in Fig. 2 of the drawings.

dependently of each other by operating the clutch mechanism in the manner heretofore 1 described.

While I have illustrated and described my be understood that it canbe applied for other purposes-such, for instance, asmacadammy invention for this purpose, instead of employing a crank on the ends of the drivingshaft E for the purpose of operating this shaft I employ a sprocket-wheel on this end of the said shaft, which is connected by means of a chain to a sprocketwheel on one of the supporting-wheels of the wagon. When this arrangement is used, the macadam or other material will be fed automatically and delivered through the chute A from the side of the wagon, thus enabling it to be distributed evenly along the road as the wagon travels forward.

My invention will also be found advantageous when applied to construction and equipment cars for use in building and grading railroads, where the material can be fed and delivered sidewise from the car.

I do not wish to limit myself to the exact construction illustrated and described, as various changes in the arrangement and construction of my device might be made without departing from the spirit and scope of any invention-as, for instance, in some cases it might be found desirable to elevate the coal This would enable the operator to carry and deliver two different kinds of material and to empty each of the said compartments separately and i nor other material as it is delivered, and this could be done by arranging the conveyer A and the chute A in an inclined position, so as to elevate the coal toward its point of delivcry, and various other slight changes might be made.

From the above description the construction and operation of my invention will be readily understood, and it will be seen that I have provided a side delivery wagon or car which can be adapted to various uses and which is simple in construction and inexpensive to manufacture, there being none of the complicated mechanisms which are usually employed in devices of this character.
